Hi all

In a typical User - Post - Comment model in Rails, every user can  
create a Post and also can create Comment, question is how to grab  
every user latest comment on specific post.

Example:

Post A have 3 user making comment  
User 1 have 5 comment  
User 2 have 6 comment  
User 3 have 2 comment

So the view I want is just the latest comment for every user:

Post A have 3 user making  
User 1 latest comment  
User 2 latest comment  
user 3 latest comment

How to do it ?

thanks
